Main Section: |
|
|
%MEM directly related to RES, percentage use of total physical memory by the process. |
|
|
VIRT total memory that this process has access to shared memory, mapped pages, swapped out pages, etc. |
|
|
RES total physical memory used shared or private that the process has access to. |
|
|
SHR total physical shared memory that the process has access to. |
|
|
|
|
|
RES is most close to the memory used by the process in memory, excluding what’s swapped out. |
|
|
This includes the SHR (shared physical memory) which mean it could have been used by some other process as well. |
